Converts a JSON Schema to a Plain Old Python Object class
Project description
JSONSchema2PoPo2
Forked from github.com/frx08/jsonschema2popo
A converter to extract 'Plain Old Python Object' classes from JSON Schema files. Similar to the Java project JSONSchema2PoJo. Currently compatible with Python 3.4+ (when using enums, otherwise any version should be fine).
Installation
pip install jsonschema2popo2
Usage
Basic:
jsonschema2popo2 -o /path/to/output_file.py /path/to/json_schema.json
Options:
- -t, --use-types - Add MyPy typings.
- -ct, --constructor-type-check - Validate provided types in constructor. Default only type checks when setting property values and not when setting them in the constructor.
- -s, --use-slots - Add a
__slots__
to each generated class to be more memory efficient. - --no-generate-from-definitions - Don't generate any classes from the "definitions" section of the schema.
- --no-generate-from-root-object - Don't generate any classes from the root of the schema.
- -tp, --translate-properties - Translate property names to be snake_case. With this enabled, inner classes will no longer be prefixed by "_" since their names won't collide with the property name.
- -l, --language - Language to generate in. Either "js" or "python".
Encode Generated Object to JSON:
import json
g = GeneratedClass()
json.dumps(g.as_dict())
Decode JSON into Generated Object:
import json
g = GeneratedClass.from_dict(json.loads(data))
JSON Schema Format
This library is largely compatible with JSONSchema2PoJo and how that library reads the JSON Schema to generate Java.
Specifically, for enumerations, this library supports setting the javaEnumNames
array in JSON Schema for an enum to give names
to the enum values that will be generated in the Python output.
